Donald Sadoway: The missing link to renewable energy | Video on TED.com

This is how the idea is introduced: Donald Sadoway is working on a battery miracle — an inexpensive, incredibly efficient, three-layered battery using “liquid metal.” Professor Sadoway explains that his angle has been to design around the oil price point, not around some wild and cool technology that can never compete economically. He goes on [...]

Projecting Water Withdrawal and Supply for Future Decades in the U.S. under Climate Change Scenarios

The sustainability of water resources in future decades is likely to be affected by increases in water demand due to population growth, increases in power generation, and climate change. This study presents water withdrawal projections in the United States (U.S.) in 2050 as a result of projected population increases and power generation at the county [...]

Nonregenerative Natural Resources in a Sustainable System of Energy Supply

Following the lead of the European Union in introducing binding measures to promote the use of regenerative energy forms, it is not unreasonable to assume that the global demand for combustible raw materials for energy generation will be reduced considerably in the second half of this century. This will not only have a favourable effect [...]

Forecasting World Crude Oil Production Using Multicyclic Hubbert Model

The objective of this study is to develop a forecasting model to predict world crude oil supply with better accuracy than the existing models. Even though our approach originates from Hubbert model, it overcomes the limitations and restrictions associated with the original Hubbert model. As opposed to Hubbert single-cycle model, our model has more than [...]

Peak Nothing: Recent Trends in Mineral Resource Production

The Hubbert-type analysis used to analyze the production history of oil is applied here to other raw materials. Many resources commonly thought of as being close to “peaking” such as lithium, helium, copper, and the rare earth elements, show no evidence of logistic behavior at any point in their production histories. Although many resources have [...]

Shortages spur race for helium-3 alternatives

The Japan Proton Accelerator Research Complex (J-PARC), based in Tokai, was supposed to be one of the leading facilities of its kind, allowing an unprecedented view of microstructures in the life and physical sciences. But when the $1.5 billion (£1 billion) facility opened in 2009, it was missing something important: helium-3, a neutron-detector material. Thanks [...]

The Physical Economy of the United States of America

The United States is not only the world’s largest economy, but it is also one of the world’s largest consumers of natural resources. The country, which is inhabited by some 5% of the world’s population, uses roughly one-fifth of the global primary energy supply and 15% of all extracted materials. This article explores long-term trends [...]
